parts for an old Stevens?

[jsdboy]

i have a really old Stevens S X S model 325 evidently made for 4 years between 1904 and 1908. it's firing pins and springs are kapoot. even though it is an old monstrosity, i like it, i can actually hit something with it when the thing fires (me and SXS's usually don't get along...............)

i have checked with Numrichs, Brpownells, etc and nothing.

i am wondering if the somewhat newer model 311's would have about the same sized parts??? any experience out there? numrichs does have firing pins for these guns.

or will it be turning the gun over to a smithy and having some pins and springs made up?

thanks for looking!
